1. K3878-VB MOSFET Product Introduction
K3878-VB is a single N-channel MOSFET in TO3P package, designed for high voltage applications. Its drain-source voltage (VDS) can reach 900V, which is suitable for applications requiring high voltage tolerance. The gate-source voltage (VGS) range of the device is ±30V, allowing flexible driving methods. The threshold voltage (Vth) of K3878-VB is 3.5V, which is suitable for a variety of control circuits. It uses SJ_Multi-EPI technology, has a relatively high on-resistance (RDS(ON) of 750mΩ @ VGS=10V), and can withstand a maximum drain current of 9A. The high voltage resistance and good switching characteristics of this MOSFET make it very suitable for use in high-voltage power management and conversion applications.
